Molecules are called autocrine regulators if they act on the same cell type as the one that produced them, while paracrine regulators, particularly if they are produced by one cell type, can regulate neighboring cells of the same organ.
In this review, the term "autocrine signalling" will be used to describe signals secreted by a cell that may bind to that cell or to a nearby cell with a similar phenotype, whereas the term "paracrine signalling" will be used to describe signals produced by a cell that that cell type cannot respond to but that other cell types can.
A paracrine ligand is a tool to spread the message from one cell type to the others, whereas an autocrine signal acts as an amplifier or a brake for message transmission. Multiple GPCR subtypes that are expressed in various cell types have been found to be capable of recognising a wide variety of ligands.
